ABSTRACT:
A method of loosening crop material jammed between a cylinder and concave grate of an agricultural combine includes attaching a winch to a portion of the combine such that the winch location is fixed relative to the cylinder. An arm member is engaged with the cylinder, and a free end of the winch cable is attached to the arm member. The winch pulls the arm member toward the winch and rotates the cylinder in a reverse direction through a portion of a revolution, and then the winch is reversed to provide slack to allow disengaging the arm member from the cylinder, and reengaging the arm member at a different location to attain a suitable orientation. The winch is then again operated to rotate the cylinder in reverse through a further portion of a revolution, and steps are repeated as required to loosen the crop material.
